Shunt equation
WebJul 10, 2016 · The classic shunt equation and measurement is therefore the gold standard in the measurement of the efficiency of oxygen uptake by the lungs. Probably the most notable deterrent to routine measurement of the physiologic shunt is the requirement for mixed venous blood samples. WebAug 9, 2006 · The Berggren equation [] is used to calculate the magnitude of intrapulmonary shunt (S), “comparing” the theoretical O 2 content of an “ideal” capillary with the actual arterial O 2 content and taking into account what comes into the lung capillary, i.e., the mixed venous content.Cc′O 2 is the capillary O 2 content in the ideal capillary, CaO 2 is the …

WebThe equation for a solar cell in presence of a shunt resistance is: I = I L − I 0 exp [ q V n k T] − V R S H. where: I is the cell output current, IL is the light generated current, V is the voltage across the cell terminals, T is the … WebSep 19, 2024 · The power input to the motor is the product of the motor current and the applied voltage. The efficiency of the motor is defined as the mechanical power output divided by the electrical power input at each calculation step. At around 10% of the motor stall torque, maximum efficiency is reached.
